Algebra.Com's Answer #504706 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! Imagine you are doing what they ask. You \n" ); document.write( "are reaching in the box and picking letters \n" ); document.write( "one at a time. \n" ); document.write( "What they are looking for is the \"worst case\" \n" ); document.write( "which is the hardest way possible to get SAT. \n" ); document.write( "So imagine this is the order in which you \n" ); document.write( "pull out letters: \n" ); document.write( "M \n" ); document.write( "C \n" ); document.write( "H \n" ); document.write( "U \n" ); document.write( "E \n" ); document.write( "5 letters so far and no S,A, or T \n" ); document.write( "-------------------- \n" ); document.write( "Now say, the nest letters you get are: \n" ); document.write( "S \n" ); document.write( "S \n" ); document.write( "S \n" ); document.write( "S \n" ); document.write( "That helps, but you only have 1 letter to make SAT \n" ); document.write( "You've got 9 letters so far \n" ); document.write( "--------------------- \n" ); document.write( "The next letters you get are: \n" ); document.write( "T \n" ); document.write( "T \n" ); document.write( "11 letters so far, but you're missing the A \n" ); document.write( "--------------------- \n" ); document.write( "The only letters left in the box are A,A so \n" ); document.write( "the next pick gives you SAT \n" ); document.write( "--------------------- \n" ); document.write( "That makes 12 letters needed to be CERTAIN that you \n" ); document.write( "have SAT because you know this the the worst \n" ); document.write( "case that can happen \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
